Study Notes

Coagulatio Externa

Via coagulationis externae, factor VII activatur per thromboplastinum tissularum (factor III)
Pathway shortcut: thromboplastinum tissulare → factor VII → complexus V → thrombinum

Coagulatio Interna

Via coagulationis internae, factor XII activatur per superficies negativae, sicut collagenum vel vitrum
Cascade reaction: factor XII → factor XI → factor IX → factor X → thrombinum

Commune Via Coagulationis

Activated factor X → thrombinum
Thrombinum → fibrinogenum → fibrinum
Cofactores necessarii: calcium, phospholipida (ab platellets)

Hemostasis

Hemostasis: cessatio haemorrhagiae quando vas sanguineum laedatur
Processus hemostasis: vasoconstrictio, aggregatio platelletarum, formatio retei fibrinae

Protectio Endothelii Intacti

Endothelium intactum vasoactive substances (PGI2, NO) secretat, quae:
- Vasodilatant
- Inhibent aggregationem platelletarum
Endothelium intactum CD39 enzyma secretat, quae ADP in AMP et Pi convertit, aggregationem platelletarum inhibens

Damnum Endothelii

Endothelium laesum collagenum exposuit
Plateltae ad collagenum adherent, von Willebrand factor plateltae et collagenum coniungit
Plateltae reactionem release (ADP, serotonin, thromboxanum A2) habent, quae plateltae aggregationem amplificant
